ANGLE-COCK HOLDER AND PIPE-CLAMP FOR AIR-BRAKES FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 792,137, dated June 13,1905.

Application iled March 24, 1905. Serial No. 251,753.

To all whom, it rmi/,y concern:

Be it known that I, ROBERT R. J oNns, a citi- Zen of the United States,residing' in Chicago, in the county of Oook and State of Illinois, haveinvented a new and useful Improvement in Angle-Cock Holders andPipe-Clamps for Air-Brakes for Railway-Cars, of which the following is aspecification.

My invention relates to improvements in angle-cock holders andpipe-clamps for airbrakes of railway-cars.

Great diihculty has heretofore been experienced in the practical use ofair-brakes on railway-cars by reason of the angle-cocks, which arescrewed on the ends of the air-brake pipe and connect with the hoseextending between the adjacent cars, becoming unscrewed from the pipeand lost. On a single railway the loss Jfrom this source frequentlyamounts to several hundred dollars per month, as I know from my ownpractical experience and observation.

The object of my invention is to provide an efficient and durable devicefor clamping or supporting' the air-brake pipe and holding theangle-cock, of simple construction, and by means of which the diiiicnltyheretofore experienced may be entirely overcome or avoided.

My invention consists in the means I employ for practicallyaccomplishing this object or result-that is to say, it consists in atwopart pipe-clamp adapted to embrace the airbrake pipe and providedwith a bracket or arm adapted to be secured to the car-frame to supportthe end of the air-brake pipe and furnished at its end with a holder orsocket to embrace the hexagonal head or end of the angle-cock, and thusprevent the angle-cock, which is threaded onto the end of the brakepipe,from becoming' lost.

' In the accompanying drawings, forming a part of this speciiication,Figure l is a side elevation of an air-brake pipe-clamp and angle-cockholder embodying my invention. Fig. 2 is a section on line 2 2 of Fig.3. Fig. 3 is an enlarged detail elevation showing a portion of thecar-frame in section with one of the clamps removed.

In the drawings, A represents a portion of a railway-car frame; B, theair-brake pipe; C,

the flexible hose connecting the air -brake pipes of adjacent cars, andD the angle-cock which connects the pipe B and hose O. All these partsare of the ordinary construction heretofore customarily in use.

F F represent my two-part air-brake pipeclamp and angle cock holder. Thepart or member Fo the clamp is furnished with an arm or bracket F2, bymeans of which it is attached to the car-frame A by bolts f. The part orclamp F is furnished with a semicircular socket f which in connectionwith the similar socket f2 receives and embraces the pipe B. The part ormember F' of the clamp is removably secured to the partF by bolts f 3,having threaded nuts f i. Each of the parts or members F Fl of the clampis provided With an integral projection or holder f 5, having aninwardly-projecting lip or shoulder f, forming a socket to receive thenon-circular or hexagonal end or head Z of the angle-cock D, and whichholder thus embraces the head or end (l of the angle-cock and preventsall possibility of the angle-cock becoming lost, even if it shouldbecome disengaged or unscrevved from the pipe B.

The inwardly-projecting lip or shoulder f of the angle-cock holder f5fits behind the shoulder' formed by the angle-cock head or end a', andthus embraces said head or end and renders it impossible for theangle-cock to become disengaged from its holder, even if it becomesunscrewed from the pipe B. Vith my device there is thus no danger orpossibility of the angle-cock being lost, even though it becomesdisengaged from the airbrake pipe B.

I claim I. The combination with an air-brake pipe and angle-cock, of atwo-part clamp embracing the pipe and furnished with an integralprojection or holder, having a socket to receive and embrace the head ofthe angle-cock and prevent the same becoming lost in case the angle-cockbecomes disengaged from the pipe, substantially as specified.

2. A two-part air-brake pipe-clamp and angle-cock holder, having asocket at its front end to embrace the head or end of the anglecock,substantially as specified.

3. The combination with an air-brake pipe and angle-cock, of a two-partclamp embracing` the pipe and furnished with an integral projection orholder, having a. socket to receive and embrace the head of theangle-cock and prevent the same becoming` lost in case the angle-cockbecomes disengaged from the pipe, Said holder for the angle-cock havingan 1nwardly-projecting lip or Shoulder fitting behind the heed or end ofthe angle-cock, substantially as specified.

4. The two-part air-brake pipe-clamp and angle-cock holder provided witha socket at its front end and an inwardly-projecting lip or shoulder tovembrace the head or end of the angle-cock and prevent the sannebecoming lost in case it becomes unscrewed or disengaged from theair-brake pipe,substantially as specified.
